A (new construction) closet in my house has a door switch that controls
a light. The switch is wired to some low voltage thermostat wire, and
I have a switch leg that runs to the actual light mounted in the
ceiling. The idea is, the door opens and the light turns on.
My thought is to use a taco one-zone relay to set this up.
I see from the taco wiring diagram pretty much how this works, but I am
puzzled about one thing. The diagram shows that the relay is connected
to a thermostat (in my case, this connects to the closet door), to a
120 vac line (feed in), to a circulator (in my case, a ceiling light),
and to a thermostat for a boiler. Is the latter there so that the
boiler knows to turn on when the relay is energized? Can I just leave
this off because I do not need a secondary low voltage signal to go to
a device when the door to the closet opens?
(Hopefully this make sense...)
